Additional TF2 features:
- Added new auto-team-scramble system:
Set mp_scrambleteams_auto to 1 (default) to automatically scramble the teams if the criteria is met
Set mp_scrambleteams_auto_windifference to set the number of round wins a team must lead by in order to trigger an auto scramble (default is 2)
- Updated how Spy disguise targets are selected to more randomly distribute the selections
- Fixed the FreezePanel background not using the correct color if you were killed by a player or building on your own team
- Server browser tweaks:
It will now encourage you to add servers to Favorites or Blacklists after you have a good/bad experience on them.
The Server Browser now automatically closes after successfully connecting to a server (opt-out via the Options-Multiplayer-Advanced dialog)

After this update:
My TF2 server crashes immediately after someone connects to it.

My CS:S server crashes somethimes. Like every 10 or 20mins
Both CS:S and TF2 servers crashes saying "Memory cannot be read" in server console. After pressing "ok" SRCDS Guardian starts the server again and the same things repeat.

My HL2MP/DM server is laggy and me and my friends get stucked somethimes in random places.

Why does Orangebox ruin our gaming? Or am I doing something wrong?

Probably because a plugin is out of date or broken because of the update.
